How to use

Mount the camera on a stable surface such as a ceiling, wall or under a covered eave at a height and angle that capture the target area. Connect the device to your recording and monitoring equipment following the manufacturer’s wiring and network instructions. Adjust the camera orientation and focus area, then verify the field of view on your monitoring station to ensure important zones are covered. Configure recording, motion detection and retention settings in the recorder or video management system according to your operational needs.

Recommendations

Place the camera at a height that balances coverage and identification detail — typically 2.5–4 meters for indoor ceilings — and avoid direct exposure to unprotected weather. Combine with appropriate lighting for consistent image quality in low-light conditions, and integrate the camera into a networked recording system with regular backups and maintenance checks.
